The IDataParameter interface enables you to implement a Parameter class, which represents a parameter to a Command object. An application does not create an instance of the IDataParameter interface directly, but creates an instance of a class that implements IDataParameter.

Classes that implement IDataParameter must implement the required members, and typically define additional members to add provider-specific functionality.

When you implement the IDataParameter interface, you should implement the following constructors:

Class

Description

PrvParameter()

Initializes a new instance of the PrvDataParameter class.

PrvParameter(string parameterName, object value)

Initializes a new instance of the PrvDataParameter class with the parameter name and an object that is the value of the parameter.
